Avulsion of the tendon of the extensor digitalis longus muscle in a Dobermann Pinscher

Avulsion of the tendon of the extensor digitalis longus muscle is a rare co ndition in young, large breed dogs or as a consequence of chronic lateral p atellar luxation in adult dogs. Current technique of fixation consists into reattaching the fragment with a lag screw at its origine in die extensor f ossa of the lateral femur condyle. if the fragment was considered too friab le and reactive to be reattached, it was amputated and the tendon was sutur ed to the joint capsula. In this present case a adaptation screw with a was her was inserted distally to the sulcus extensorius through the tendon. The proximal part of the tendon was sutured to the joint capsula. The postoper ative result was ecxellent, with recovery of full function of the Musculus extensor digitalis longus.
